Rear sway bar performance

As the sway bar for VW 1302 Super Beetle is prepared, some trial fitting must be performed. Though the lateral torsion bar supporting mounts exist, but the linkage arm lower supporting brackets do not, because of IRS trailing arm rear end constructive design.

I checked about this problem when rear brake shoe clearance adjustment, the original brackets for swing axle except IRS are not applicable because of upper reason, so any bracket should be re-designed and be fixed well to support the impacts from the ground.
I know before doing those modification by the experience with SUBARU Impreza GF 1800cc model, originally without rear sway bar but applied by myself achieving good results.

We can find out linkage rod with ball joints in many replacement parts, I've some confidence to make up sway bar linkage construction for VW Super Beetle establishing anti-rolling effect utilizing most of genuine parts without destroying the balance of factory setting design.
Now the steering performance is in strongly under-steering property because of rear breakage, this unacceptable phenomena would become better after the rear sway bar application.

BC7 SUBARU Legacy LSi US model has now neutral steering action performance when 4WD drive train is applied, but in case of FF traction under- steering response is played.
Rear total toe setting also increase the rate of under-steering property, rear tread value also much to do with the steering reaction, wider rear tread invites under-steering one.

A wheel spacer does exist to adjust this kind of performance adjustment not for the appearance.
